Cost-benefit analysis of liquefaction mitigation strategies

This paper presents a cost-benefit model as part of the options appraisal process to evaluate
alternative ground mitigation interventions to reduce vulnerability and/or improve resilience of
built assets to earthquake induced liquefaction disaster (EILD) events. The paper presents a review
of alternative approaches to cost-benefit analysis and develops forward looking (risk based) and
backward looking (impact based) cost-benefit models that can be used by practitioners and policy
makers to improve community resilience through better contingency and disaster management
planning. The paper customises the models against EILD scenarios and identifies the cost and benefit
attributes that need to be assessed if the models are to be effectively integrated into a resilience
assessment and improvement framework for improved community resilience to EILD events.
